Embodiment
Technical scheme is elaborated below in conjunction with drawings and examples.
As shown in figure 1, the foot clipboard of the present invention includes protective layer 1, sensor base plate 6 and bottom plate 9.Protective layer 1 wraps
Including the flexible plastic film being covered on sensor base plate 6, protective layer 1 is arranged with system switching 2, LCDs 3, therefore
Hinder indicator lamp 4 and relay indicating light 5；Pliable pressure sensor on sensor base plate 6 is to be led based on MEMS technology using pressure-sensitive
Electric silica gel and pressure drag electric slurry customization is process, in array distribution, and it is corresponding according to the induction region on the surface of protective layer 1
Set, reticular density is adjustable, such as 2 points/cm2, 4 points/cm2, 8 points/cm2, measurement range 10-5000kPa, pliable pressure sensor
7 front ends are provided with data acquisition module 8；Power supply module 13, message processing module 10, data transmission module are provided with bottom plate 9
12.Power supply module 13 is connected with message processing module 10, data transmission module 12 and data acquisition module 8, including lithium battery,
Ni-MH battery or lead-acid battery built-in power, charging inlet 14；Message processing module 10 is adopted with data transmission module 12, data
Collect module 8 to be connected, including signal condition unit, micro-control unit and data storage cell, the micro-control unit be MCU or
ARM；Data transmission module 12 is connected with data acquisition module 5, including wireless data communication unit and usb 11；Data are adopted
Collection module 8 includes signal receiving circuit, signal amplification circuit and data collecting card, and signal receiving circuit is bridge circuit, can be with
Improve sensor accuracy and signal stabilization, signal amplification circuit use operational amplifier.
As shown in Fig. 2 the foot writing plate surface of the present invention is provided with power switch 2, LCDs 3, indicating fault
Lamp 4, relay indicating light 5 and 9 induction zones based on pliable pressure sensor, including " moving to left " induction zone 1.1A, " moving to right "
Induction zone 1.1B, " left cancellation " induction zone 1.2A, " right cancellation " induction zone 1.2A, left foot rest area 1.3A, right sufficient rest area
1.3B, " left determination " induction zone 1.4A, " right determination " induction zone 1.4A, writing induction zone.
As shown in figure 1, the gait exchange method based on pliable pressure sensor of the present invention, its job step are：
(1) when, working, 2 are turned on the power switch, relay indicating light 5 lights amber light, foot clipboard normal boot-strap；
(2) left foot, is placed on left foot rest area 1.3A, right crus of diaphragm is placed on right sufficient rest area 1.3B, and relay indicating light is bright after 2S
Green light is played, foot clipboard can start working；
(3), now, left (right side) pin is motionless, and right (left side) pin leaves the right side (left side) pin rest area 1.3B, to writing induction zone 1.5
Write, it is noted that need a pin being positioned over left/right pin rest area 1.3A/1.3B always during writing, with another pin
Write, i.e., when right crus of diaphragm is write, left foot is placed on right crus of diaphragm rest area 1.3B；When i.e. left foot is write, right crus of diaphragm is placed on left foot and put
Put area 1.3A；Left/right " confirmation " induction zone 1.2A/1.2B and left/right " cancellation " induction zone 1.4A/1.4B is left for convenience
The alternation of right crus of diaphragm and set, function phase is same；
(4), pressure information is carried out denoising identifying processing by foot clipboard internal information process chip, extracts individual character
Feature, start to write order, stroke, shape, profile, radical etc., is matched to the word of user with the template in Chinese character database,
Unascertainable word then then provides similar word according to probability, after Chinese character matching, after Chinese character information is transferred into computer progress
Continuous processing, while Chinese character included with larger font to list multiple similar words in LCDs, and according to probability, by class
Like word to be shown compared with small font, selected for operator；
Operator with pin press left/right " it is determined that " induction zone 1.4A/1.4B chooses the Chinese character that is currently shown with larger font,
If Chinese character is not the Chinese character shown with larger font, and in the Chinese character to be shown compared with small font, then operator can be pressed with pin
" moving to left " induction zone 1.1A or " moving to right " induction zone 1.1B selects to think the Chinese character of expression, after choosing, left/right " it is determined that "
Induction zone 1.4A/1.4B confirms, if not having the Chinese character to be write in the Chinese character of display, presses left/right " cancellation " induction zone
1.2A/1.2B cancels this this input, pressing " moving to left " sensing in 3S after left/right " cancellation " induction zone 1.2A/1.2B is pressed
Area 1.1A represents the current Chinese character of deletion, and continuous pressing represents continuous deletion；
(5) after, selecting Chinese character, foot Write can carry out association's prompting, i.e., the Chinese of word can be formed with current Chinese character
Word, now pressable " move to left " induction zone 1.1A or " moving to right " induction zone 1.1B to select to think the associative Chinese character of expression, pass through
Pressing left/right " it is determined that " induction zone 1.4A/1.4B confirmed；Pressing pressing left/right " cancellation " induction zone 1.2A/1.2B or
Person directly carries out writing then this automatic closing of association's prompting of next Chinese character；
The foot clipboard and its exchange method combination true man's many experiments based on pliable pressure sensor of the present invention, if
Simple and comfortable operation, the identification reliable foot motion specification of relative robust again are counted out, can recognize that complex word writing is dynamic
Make and export corresponding stereotyped command, it is overlapping to avoid occurring during follow-up newly-increased action excessive action, abides by as far as possible during design action specification
Vivid, readily understood easy-operating principle is followed, then according to the relative position relation of both feet during operational motion and corresponding plantar pressure
The timing variations of distribution are distinguished and differentiated, its specific identification process is as follows：
Vola action starts, and pressure span starts to occur continuously to change in the range of vola, calculates each frame plantar pressure
The pressure dot center of region of variation, pressure span center point set, Center of Pressure point is carried out curve fitting, judge the song of fitting
Line is straight line or broken line；All data traversals finish, and carry out action differentiation：It is after the pressure change region fitting in vola
" one ", and direction is from left to right, judges output for horizontal or point；Be " Shu " after the pressure change region fitting in vola, and direction from
Top to bottm, judge output and carried to erect or erecting；Be " ┐ " after the pressure change region fitting in vola, and direction from left to right again oneself
It is upper downward, judge output for cross break；Wei " ∟ after the pressure change region fitting in vola ", and direction is from up to down again from left-hand
The right side, judge output for perpendicular folding；It is after the pressure change region fitting in vola " ⌒ ", and direction right-to-left, judge output for it
His stroke；All strokes are collected, are compared with the action stored in foot lteral data storehouse, it is determined that differentiation action institute is right
The word answered, and export.
It is described above, it is only the embodiment in the present invention, but protection scope of the present invention is not limited thereto, and is appointed
What be familiar with the people of the technology disclosed herein technical scope in, conceivable conversion and remodeling can be managed, also should be regarded as by
It is included within the scope of the present invention.
